ELECTRICAL NECTER.

Application led April 5, y1919. Serial N0. 287,863.

I To all .'wlwm it may concern.'

` composed of a continuous piece of spring wire'lor other suitable material and which provldes two cooperative jaws to clampingly engage the'terminal or other electrical de? vice to whichthe connecter is applied.

By making the connecter of a continuous piece of metal the two jaws are always in circuit and .insulation of any part of the article by lcorrosion is prevented.

Another object of the invention is to providea connecter vof the type mentioned which by the extreme simplicity of its construction combines strength and durability with low cost of production.

With these- 'and other objects in view, all

of which will fully appear in the course of 'the following description, my inventionconsists in the novel constructions and combinations of parts shown in the accompanying drawings inthe various views of which like views are similarly designated andy in which- Figure 1 is a plan view of the improved connecter in its preferred form,

Figure 6, a plan View of two connectersof the improved constructiony connected for ap- Figure 5, an enlarged section taken on thel tive jaws 2 at the ends of substantially v aline-d Shanks 3 formed of laterally extend-` ing parts of convergent members 4 which at their lapping ends are. bent into eyes 5 for their connection by a coupling-bolt 6.

The Shanks cross each other adjacent -their L ends at which the jaws are formed and a spring-loop 7 between the members adjacent their connected ends, holds the jaws yieldingly together.

In order to form the entirefclamp of one -continuous piece, the wire 1s doubled, its

central portion is coiled to form the spring loop 7 and its doubled portions at'opposite sides thereof are bent toform the springlegs 8, the Shanks members 4. Y

The jaws are preferably made by bending the doubled wire into triangular form as shown in Figures 2 and 4 ofthe-drawings and they are covered by plates 9 which are bent around their sides and which atetheir edges corresponding with the' ends of the jaws, are bent and serrated to provide teeth 10 which bite into the terminal or other object placed between the jaws and thus assure their firm and conductive connection therewith.

This clamp is in practice fastened at the end of a conductor of electricity by' a clasp 13 which is attached to the bolt 6.

The clasp consists of a strip of metal having an eye 14 for its connection with the bolt and one or more pairs of opposite .pliable wings 15 which are bent around the conductor as clearly shown in Figure 1 of -the drawings.

In order to assure a flow of current to both the jaws of the clamp and prevent their insulation byv corrosion at the connected ends of the wire of which the device is composed, the yends are welded together as shown at 16l inv Figure 2.

After the parts of which the connecter is composed are'formed and .assembled as hereinbefore described, the entire article is electrically lead-coated as` a protection against the corrosive .activity of the acids commonly used in batteries of the type to which my invention is most frequently applied.

3, the jaws 2 and theA In `'the .modified construction illustrated I in Figure 7 the end portions of the wires instead .of being joined at their extremities. are wound around the convergent legs 8 of the spring loop 7.

The connecteris attached to the conducv the convolutions 17 o tor of electricity by placing an end thereof between one of the legs of the spring and the end portion of the wire wound around the same.

The method of using the connecters is too Well-known to those skilled in the art to rel'q'uire further explanation at this point, it'

l of batteries 19.

l forth in the followingl claims:

Although I have shown but two diferent forms of my invention in the present application I know that it is possible to make other modifications too numerous for separate illustration, and I desire it understood that such modifications may be availed. of within the spirit of my invention as set 1. An electrical connecter composed of a continuous piece of doubled wire the middle portion of which is looped to provide a spring, and which is bent to form convergent legs at opposite sides of the loop, members "extending along said legs and joined at one of their ends, and jaws composed of the porltions of the wire between saidI legs and said members.

2. An electrical connecter composed of a continuous piece of doubled wire the middle portion of which is looped to provide a spring, and which is bent to form conver ent legs at opposite sides of the loop, mem ers extending along said legs and 'oined at one of their ends, jaws composed o the portions of the wire between said legs and said members, and a bolt connecting the joined ends of the legs. f

3. An electricalfconnecter composed of a vcontinuous piece of doubled wire the middle portion of which is looped to provide a spring and which is bent to form convergent legs at opposite sides of the loop, members extending along said legs and joined at one of their ends, jaws composed of the portions of the wire between said legs and said members, a bolt connecting the joinedy ends of the legs, and a fastening fora conductor of electricity connected to the bolt.

4. An electrical connecter composed of` a continuous piece of doubled wire the middle portion of which is looped to provide a spring and which is bent to form convergent legs at opposite sides of the loop, members extending along said legs and welded together at one of their ends, and jaws composed of the' portions of the wire between said legs and said members. c

5. An electrical connecter composed of a continuous piece of doubled wire the middle portion of which is looped to provide a spring and which is bent to form conver ent legs at opposite sides of the loop, mem ers extending along said legs, and fastened at their ends, and jaws composed of the portions of the wire between said legs and said members. l

6. An electrical connecter composed of a y continuous piece of doubled wire the middle portion of which is looped toa provide a spring, and which is bent to form conver ent legs at opposite sides of the loop, mem ers extending along said le s, and jaws composed of the portions o the wire between said legs andsaid members.

In testimony whereof I have affixed my signature.
